Typical leaking on RV's unless they are fiberglass two piece units, hence reason to never buy one. Great work on repairing it, without a shop it's next to impossible to repair them or restore them. So what was that a beverage truck, frame looks like mine.

Every thing except the air and microwave will run off the truck. I plan on a small generator when parked. Where we will be using it there is usually no power.

I suggest going with solar IMHO, and using the small genset as backup. How long you plan on going "off grid" when scooting around? Go look at Frankenstein on here, that's my build and might give you insight on solar.

Crossed the US last month and only used the generator 3 times from Washington state to Montana and on to Texas in 2 weeks. What's your overall use for it, full time or part time?
